The gear 24 which is loosely mounted o n the shaft 33 will then rotate, operating with it the gear 25 and shaft 26. As the shaft 26 completes a revolution, the roller 28 on tbe eem 47 will fesen .enf-rese .tb-eymenlber 33 preventing a further, rotation. Simultaneous withtbie operation, tbe member 33 willengage the arm 29, which will disengage the members 27 ofthe clutch 2 8.

Mounted on the vframe 54 is a substantially L-ebeped supportner ann .67. Pivotelly een nected to this arm 'at 72 is the member 67a., which is provided with fingers 68 designed tobe retained in position by ya chain 7 1 engagingthev loop. in the fingers and travelling over the pulleys 69 and 70 and .connectedy at its other end to the wing 5 6o` l in each wheel may be arranged at will.`

vrigidly fastened together.

which it will be seenthat asfthe basket lowers todeposit the stookthe'chain 71 is slackened andthe fingers throughforce of gravity vas- ,sumethe-,positiom shown in .dotted lines in Figure 2, -tocat'ch any, sheaf .which may be discharged before the basket returnsV to its position and t-hen to drop it into the basket when. it reaches its position.

The foregoingf fa. description of the stooker and its operation as combined with the remodeled binder when the receiver is dumped at will by the driver. Y f

When it is desired that the machine should be made to automatically stook when a given number of sheaves are deposited in the basket, mechanism is provided for this purpose, as illustrated in Figures 4 andv 5, in which 36, as previously mentioned, is the binder needle mounted to oscillate on a shaft i 49 and adapted to operate in conjunction with the delivery of the grain from the deck 50. At the end of the rod 44,1remote from the bevelled gear 24 thereon is a shaft 41 journalled on a bearing secured to the frame at 51 and adapted to carry thereon a disc' member 41 comprising three 'ratchet wheels each provided with notches in rotation, namely 7, 9 and 11 respectively as here illustrated, valthough the number of ratchet' wheels in the disc and the number of notches These notches are intended and do correspond to the number of sheaves in a stook and can be set accordingly. This is accomplished by a hand lever 39, adapted to engage Y with a notched segment 39l to operate a dog 37 which in turn will engage with the teeth in one of the wheels in the member 41, as

illustrated in Figure 5, by which it will bey seen that when the needle 36 returns to rest it will engage with the dog 37 in one of the notches in the member 41 turning the latter one notch. This operation will be repeated at the completion of each'sheaf. The dog 37 is returned by means of a spring 38 and as the disc member 41 completes its rotation 'the designated number of sheavesvfallinto .the basket and on the arrival of the last sheaf the pin 42 forces a dog 43, connected to the rod or cable'44 and pivotallysupported l on abracket 44a of the frame, backwards im- These wheels are rollers.`f on the..:side1j ofthe .main frame, wwhilethe upper portion'.ofthe'stookerframey `isheld inv .contac'twith the side 77.of the mainframe and :theifarend of a:lever y75l engages..themember 578.011 Vthe binderY head 1 -framefwhich .thefdriver on the1seat83 may operate.: to suitcthe length of grain andi lock the. samer-With thev dog of-thel leverI in thev notches 7G. The rear end of the-packer shaft l2O is vsquare, and slides in the squarel f hole or bore of the member 19 when the binder head and stooker are shifted.

It will vbe noted that the binder' head is much higher above the ground than 'is the i case with the ordinary vbinder and that the binder head frame is slidably operable on.` the main frame and in order to facilitate this lslidable operationthe Vpacker shaft 20 is formed square at the end, as illustrated n Figure 12. n v It is obviousv that many changes may `be made in the arrangementand details ywithin the scope of ourinvention.

What we claim as our invention is: n 1. In a combined binder and stooker, a concave receiver divided at the bottom to receive the sheaves for a'lstook, means for turning the forward end of the receiver downward for the purpose of depositing the 'sheaves on the ground in the form of a'stook,

and means for spreading the two parts 'of the receiver by gravity at the lower end for the purpose Vof straddling the stock as thema.-

chine moves forward.' Y

2.v In a combined binder and stooker, a two-part receiver, means for turning the forward end of the receiver downward yto deposit the sheaves n the form of a. stock, means for operating the two parts of the receiver to straddle they stook, and means for `retaining the said parts togethenand means for actuating the receiver comprising `acrank-shaft in combinationwith a link and.k

bell-crank.

3. In a stooker having afreceiver composed of two parts, bell-cranks'arranged to hold the parts of the receiver together and in po sition, and loops toy permit the twoparts `to spread bythe 4'force of gravity when lowered,

all as andfor the purposes described. f

4. In a stooker, a two-part receiver, crank-` shaft means for operatingk thereceiver, and

means for controlling Vthe movement of the I crank-shaft when the receiver is in position to receive the sheaves. Y 5. In a combined binder and stooker,`a receiver, means for retaining the sheaves whenv bound, means for conveying the sheaves to the receiver, means for operating the stook-y er, and means adapted to engage with' said `means to regulate the number of sheaves in a stook and comprising ratchet wheels adapted to form a disc,` a dogactuated by the binding apparatus and vdesigned to engage onevof theA ratchetr` Wheels :n said dise, and

means on the 'dise adapted to engage with theoperatng means to operate the stookei.

6; In acombned binder yand stooker, a frame, stookng mechanism and -bnder head supported ony Said frame,4 meansrfor adjusting the frame-:forwards and backwards With respect fto the binder, as and for the purpose 7. In combined-binder Yand stooker, a 10 framework', means for Shifting thexframework, a binder head and `stooker Vsupported on said frame, anti-friction rollers `ac'lapced to reduc-e friction between thefshftngparts in Contact. l f e
